    4747It also allows for a better control over coupling orders and, in particular, for the separate computation of linear and quadratic EFT contributions at NLO.

    49 The {{{2.X.X}}} series of MadGraph5_aMC@NLO should be used for event generation (i.e. beyond fixed-order computations).
    50 It can however not handle four-quark operators at one-loop.
     49The {{{2.X.X}}} series of MadGraph5_aMC@NLO cannot handle four-quark operators at one-loop and (in general) {{{cpG}}}.
    5150The model should in that case be loaded with the {{{no4q}}} restriction card (doing {{{import model SMEFTatNLO-no4q}}}) which excludes four-quark operator coefficients.
    52 An exception is single top-quark production in which the colour singlet {{{cQq13}}} and and octet {{{cQq83}}} are available in {{{2.X.X}}}.
    53 For the latter, see however the specific instructions below about "loop filtering".
     51An exception is single top-quark production in which the colour singlet {{{cQq13}}} and and octet {{{cQq83}}} can be included in computations with the {{{2.X.X}}} series of MadGraph5_aMC@NLO.
     52For that particular case, see however the specific instructions [#Topquarkproduction below] about "loop filtering".
